摘要： A method (100) in a network node serving a User Equipment (UE) capable of network assisted interference cancellation is disclosed. The method involves a signaling (104) of an indication to the UE indicating whether the UE should enable or disable (108) the network assisted interference cancellation, or whether the UE should autonomously choose (110) to enable or disable the network assisted interference cancellation. The enabling or disabling is done for at least one of demodulating the downlink channel or computing the channel state information. The method further involves a receiving (106) of information from the UE about whether the network assisted interference cancellation has been used by the UE for at least one of demodulating the downlink channel and computing the channel state information. A related method in a UE is also disclosed, together with the network node and the UE as such.

摘要： A technology is disclosed for decoding a received signal at a wireless device. A first receiving process is performed comprising a decoding of the signal giving a first decoded result. It is determined if the first decoded result is correctly decoded. If so, the first decoded result is provided for downstream processing.

摘要： A method and system to reduce a probability of incorrect interruption of an uplink transmission of a wireless device are disclosed. According to one aspect, decoding of a sequence of bits obtained from a signal received by the wireless device is performed without knowing whether the sequence corresponds to one of a grant for uplink transmission and noise. Decoding of the sequence of bits is performed to determine a probability metric associated with a first m bits of the sequence, where m is an integer greater than 1. The probability metric is compared to a threshold. The received signal is interpreted as having a grant sequence if the probability metric is greater than the threshold. The received signal is interpreted as noise if the probability metric is not greater than the threshold.

摘要： Several advanced features in wireless network, such as multi-carrier operation, multi-RAT/multi-mode transmission, etc., may not be exploited to their fullest potential when uplink transmit diversity is used in conjunction with them. Several techniques described herein address these problems. An example method begins with the evaluation (610) of operating conditions for a mobile terminal transmitter and, based on the operating conditions, selectively activating or deactivating (620) multiple-antenna transmission by the mobile terminal. The operating conditions that are evaluated include,in some embodiments, the applicability of power backoff (maximum power reduction, or "MPR"), including whether Additional MPR (A-MPR) or power management MPR (P-MPR) are applicable. Other operating conditions that are evaluated may include uplink data rate requirements or limitations for the mobile terminal, and/or the actual or estimated status of the battery in the UE.

摘要： A user equipment, UE,(14) and a radio network node (12) can perform multiple input multiple output,MIMO,communication. The UE determines a precoder (50, 54) used in the radio network node for transmitting signals from multiple transmit antennas to the UE. Based on the determined precoder used, the UE determines receiver parameters (22, 60A, 60B) for receiving MIMO signals from the radio network node, and configures the UE to receive MIMO signals from the radio network node in accordance with the determined receiver parameters. The radio network node may provide information for transmission to the UE indicating the precoder used in the radio network node to permit the UE to determine a receiver configuration for receiving MIMO signals based on the determined precoder used by the radio network node.
